HYDAC Heat Exchangers and Cooling Systems –a Cool Solution for Every Application

Hydraulic and lubrication systems play a major role in almost all stationary and

mobile machines. The uids used transmit power, provide lubrication,

channel away heat and protect from corrosion.The quality of the uid is the ngerprint of the whole system. The temperature

control and purity of the uid, for example, are crucial factors for the state of

the entire control equipment in mobile-hydraulic applications.

In all hydraulic systems, energy is converted and transported.

This involves some energy being lost, in the form of heat. The task of the cooling

systems is to dissipate the heat.

Efcient cooling systems can help to lengthen the service life of the operating

uids and lters used and reduce life cycle costs.

HYDAC Cooling’s product range includes coolers, heat exchangers and

cooling systems for almost all industries and applications.

We can cool not only hydraulic systems but also electric drives and motors,generators, inverters and transformers.

Our cooling systems enable gearboxes to be cooled and lubricated and mobile

working equipment and vehicles to keep going for longer.

Conserving Resources and Protectingthe Environment with Intelligent Solutions

As resources are limited, sustainability is a global challenge. Energy efciency

is an important step towards greater sustainability in stationary and mobile technology.

HYDAC has spent years developing intelligent and energy-efcient products andsolutions to help you to make your operations sustainable.

Alongside cooling systems that are particularly economical in their use of availableresources, we offer systems and solutions that make use of the heat that is ofteninevitably lost in industrial processes, for example by returning it to the process wateror the heating circuit.This allows you to save natural and nancial resources in the long term.

Using energy efciently is only one way to increase sustainability. Other important

methods are increasing service life and optimizing new and existing plants inhydraulics, uid technology and electronics.

The main features of energy-efcient components and systems are as follows:

l

Lightweight and compact design lOptimized drive power

lSpeed-controlled fans

lControl based on ambient conditions

l Low noise level

lEnergy-efcient refrigeration technology

Energy-efcient model series

can be recognized by their green“HYDAC ENERGY SAVING” seal.

HYDAC Cooling Modules for Engines of all Emission Levels As a result of the increased requirements concerning energy efciency and

noise development in mobile machines, cooling systems for these vehicleshave to be designed to the limits of physical possibility.

By combining multiple cooling circuits, integrating functions(such as tank and lter functions) and using electrical and hydraulic fan controls,

HYDAC mobile coolers are well-equipped to deal with all requirements.

The advantages of energy-efcient engineering include:

Development Resources and Software Development

HYDAC provides support throughout, from risk analysis to certied machine function.

HYDAC provides support and advice to the customer, as required, throughthe entire product development cycle – from design and simulation, right through to

the application software, commissioning and series production.

Design Programsand the KULI Simulation Software

To help you to nd the perfect cooling solution for your particular requirements,

you can make use of the design software “Cool-IT” or the design program forsoldered plate heat exchangers. This is important because only correctly congured

components can provide an efcient cooling that saves energy, reduces strainto your budget by minimizing “Life Cycle Costs” and extends the operational reliabilityof your systems.

We can gladly assign you a specic HYDAC contact to help you with optimizing

your design to suit your needs.

With the KULI software it is possible to scrutinize the thermal economy ofa machine in its entirety. But KULI can also be used to design individual coolersor heat exchangers. Reliable design of coolers or cooling systems is made possibleby the simulation of the various heat balances of the individual componentsbased on the measurement data of a model heat exchanger in the wind tunnel.

At HYDAC, a team of development engineers work with the above-mentionedsimulation methods to optimize existing components and systems and to indicate

new solution approaches, including customer-specic ones.

Air CoolersIndustrial / Mobile

General

Air cooling is a simple meansof dissipating heat, a by-product

of the efciency losses, within industrialand mobile machines.

The uid – usually oil or water-glycol –ows through a cooler. A fan draws airand drives it through the cooling element.Thus, there is a temperature differenceand heat exchange takes place resultingin an increase in air temperature whichis then released in the environment.

This process reduces the averagetemperature of the uid up to a fewCelsius degrees over the actualenvironmental temperature.

It is possible to install an air coolerin almost every situation, with a minimumimpact on the existing lay out.The operating costs are correspondinglylow and can be reduced furtherby using a speed-controlled fan.With new designs using special, low-noise fans and optimised air ducting wecan also offer coolers with outstandinglow noise emissions.

A wide range of coolers is available,with either axial and radial fan designs.

AC, DC electric drives and hydraulicmotors ensure versatility in catering

to a variety of applications and ambientconditions.

Test rigs

Field measurements or tests carried out under real-lifeconditions are important methods to analyse the coolerperformance and suitability for specic applications.Constancy and accuracy of the instruments usedfor measurments are essential requirements.Only in thus way changes in the cooling system,e.g. the position of the fan in the fan housing,can be accurately quantied.

HYDAC test rigs fulll all requirements in termsof testing accuracy and have been certiedby TÜV Süd.

The test criteria and the testing equipment to be usedare specied in the test procedures. The cooling capacityvalues indicated by HYDAC were derived followingthe specication EN 1048.

Test rigs for measuring cooling capacity with

l Hydraulic oil l Gear oil l Water glycol l Charge air

Pressure pulsation test rigsOil coolers in the primary ow are particularly affected by changing pressure loads.Regular tests according to ISO / DIN 10771-1 are performed in order to validatea cooler for its area of application.

Wind tunnel

Carried out in order to determine the performance data of cooling elementcombinations and to provide a database for cooler calculation usingthe simulation software KULI.

Thermal shock test rig

To simulate extreme operating conditions in terms of temperature.

Further tests:

l Noise measurement l Vibration tests l Burst test l Leakage test l Corrosion tests in the salt spray chamber l Cold chamber l Thermal imaging camera

Development

Since product life cycles get shorter, it is necessary to developemultiple realiable versions of a new cooler design as soonas possible. Technical simulation plays an essential rolehere because it helps reduce development costs and times.Moreover, simulation as part of the development process resultsin more accurate design and optimization, long before theprototypes are produced. Last but not least,real-life tests canbe kept to an absolute minimum.

With KULI software is possible to assess the heat management

of a machine as a whole. But it can also be used to designindividual coolers or heat exchangers. By simulating variousheat balances of individual components based on themeasurement data of a model heat exchanger in the windtunnel, reliable coolers and cooling systems are the results.

In addition to KULI, computational uid dynamics (CFD) arean important method to optimise coolers, heat exchangers and

cooling systems. Its purpose is to solve any given uiddynamic or thermodynamic problem using numerical methods.For example, CFD can be used to analyse the effectsof real, customer-specic installation situations on the coolerperformance.

Finally the FEM method, i.e. the numerical analysisof problems in structural mechanics and thermal mechanics,is an important tool in development-stage simulation.

Above all, it is used to assess structural stress and reduce

hot spot stress in order to extend service life.

A team of development engineers by HYDAC workswith the simulation methods depicted above in orderto optimise existing components and systems and to identifynew approaches to solutions, including custom solutions.

Cooler Selection

The size of the cooler depends on various factors:

l the temperature difference between the medium and the ambient air l the ow rate of the medium through the cooling element l the ow rate of the air through the cooling element (fan speed) l the design of the ns and turbulators

The following data is required for selecting the correct cooler:

l the cooling capacity required (power dissipation of the system) l the medium to be cooled

l ow rate of the medium being cooled l maximum medium inlet temperature into coolerl maximum ambient air temperature (air temperature onto cooler)

l altitude and ambient conditions

If the required cooling capacity is not known, then it can either be calculatedfrom the tank heat load or estimated from the installed electrical power.

Determining the Cooling Capacity from the Tank Heat Load

Designations:

PV

Required dissipation, cooling capacity [kW]

P01 Specic cooling capacity [kW/K]

V Tank volume [l]

δOil

Density for mineral oil: 0.915 [kg/l]

CPOil

Specic heat capacity for mineral oil: 1.88 [kJ/kgK]

ΔT Increase in temperature in the system [°C]

t Operating time [min]

T1

Oil temperature required [°C]

T2

Ambient temperature of the air [°C]

In this case, the required dissipation is determined for systems and machines that arealready in operation by rst measuring the temperature increase in the medium overa dened time period (but before the temperature stabilises). The heat load of thesystem can be determined from the available data.

Example:The oil temperature in a system increases from 20 °C to 60 °C over a periodof 30 minutes, the tank capacity is 400 l.

Calculation of the cooling capacity:

Estimating the cooling capacity from the installed electrical powerIf the plant is not yet in operation, then the expected heat load can also be estimated:without throttling, it is approx. 15 – 20 % of the drive power, with throttling,it is up to 30 % of the drive power.

l Converters

l Machine tools

Options

Integrated pressure bypass valve(IBP) / Integrated thermal pressure

bypass valve (IBT)The bypass channel is integrated in thecooling element. If a particular pressureis exceeded, the IBP opens the bypasschannel, thereby protecting the coolingelement from too high a pressure.Furthermore, the IBT only opens the

cooling element path once a particulartemperature has been reached.

ATEXThe AC-LN (without pump and lter)is also available for operation in gasand dust explosive areas. The ATEXcertication applies for a frequency of50 Hz and 60 Hz.

MarineThe MAR version is for aggressiveambient conditions, such as industrialatmospheres, high humidity or high saltcontent, which place great demands onthe corrosion resistance and robustnessof the materials used.

Cold Climate / Hot ClimateUse in extreme ambient conditions:Cold Climate to -40 °C,Hot Climate to +60 °C

The various versions can also becombined. Our technical salesdepartment will be happy to assistyou further.

Air Cooler Industry AC-LN 8-14 / ACA-LN 8-11 / ACAF-LN 8-11

General

The AC-LN 8-14 air cooler series canbe used in all areas where either oilor water-glycol is to be cooled with air.The coolers with an axial fan can beused in the return line as well asin the bypass ow.

The wide range of accessoriesand optional versions mean thatthe coolers can be adapted exiblyto various applications.

Product Features

The air ow of the cooler has beenoptimized by the use of a moreefcient axial fan and a varietyof housing modications. As a result, the AC-LN series 8-14 is especiallyefcient and quiet.

The cooler can also be used in thebypass ow by attaching a boost pump. An additional lter enables continuousltration of the medium; the coolercan then be connected as required.

Options


bypass valve (IBT)The bypass channel is integratedin the cooling element. If a particularpressure is exceeded, the IBP opensthe bypass channel, thereby protectingthe cooling element from too higha pressure. Furthermore, the IBT only

opens the cooling element path oncea particular temperature has beenreached.

Large coolersCoolers with a higher cooling capacitythan standard are also available asspecial versions.

Speed control: AC-LN MIThe integrated frequency converterenables stepless speed controldependent on the oil temperaturein the cooling element.

ATEX

The AC-LN (without pump and lter)is also available for operation in gasand dust explosive areas. The ATEXcertication applies for a frequencyof 50 Hz and 60 Hz.

MarineThe MAR version is for aggressiveambient conditions, such as industrialatmospheres, high humidity or highsalt content, which place greatdemands on the corrosion resistanceand robustness of the materials used.

Cold Climate / Hot Climate

Use in extreme ambient conditions:Cold Climate to -40 °C,Hot Climate to +60 °C

The various versions can also becombined. Our technical salesdepartment will be happy to assistyou further.

Note:

We recommend maintaining a minimumdistance to ensure an unimpeded airinlet and air outlet. For sizes 8-11 thisis half the height of the cooling element(A/2); for sizes 12-14 it is a quarterof the element height (A/4). Anythingbelow the minimum distance caninuence the cooling capacity and thenoise emissions.

Product Features

AC-LN MI coolers use high efciencyaxial fans driven by a frequency inverter.This guarantees immediate adjustmentto required cooling performance underchanging load conditions.

l Variable speed The inverter controls the fan speed inorder to have a constant temperature.

l

Plug and Play Simple installation thanks to theintegrated frequency inverter andtemperature probe.

l Lower operating cost The electric power is required onlywhen cooling power is neededallowing lower power consumption.

l Lower average noise level When less power is required thecooler generates less noise.

l PT1000 Temperature probewith probe holder

Accurate and reliable temperature

measurement, no need to drainthe cooling system when probereplacement is needed.

l Fail-Safe operation Operation at maximum speedin case of Probe failure detection(open or short circuit).

l Own safetyIf during operation the electronicoverheats, fan speed dropsautomatically.

l Software interface A user friendly interface is available

to check and modify all theparameters directly on site(see also Technical Data).

Options


bypass valve (IBT)The bypass channel is integrated in thecooling element. If a particular pressureis exceeded, the IBP opens the bypasschannel, thereby protecting the coolingelement from too high a pressure.

Furthermore, the IBT only opens thecooling element path once a particulartemperature has been reached.

Air Cooler IndustryOSCA / OSCAF 0-3

General

The low noise coolers of OSCA / OSCAFseries are mostly used in small andmedium hydraulic systems. Compact andefcient they offer high performance witha low noise level in a modular design.

The OSCA models with integrated oilcirculation pump provide efcient off-line cooling of the hydraulic uid. TheOSCAF models with integrated (inside-outside) lter provide additional ltration,using the latest high capacity lter dirtholding development.

Product FeaturesInstalled off-line, the OSCAF providesefcient cooling and ltration of thehydraulic uid regardless of the dutycycle of the hydraulic system. And,the cooler can be sized perfectly tothe necessary cooling performance,rather than to the maximum return-lineow rate. Off-line installation will alsoeliminate ow variances of the hydraulicuid and resulting pressure spikes whichpotentially could lead to a prematurecooler failure.

General

For applications in potentially explosiveareas are the air cooler series AC-LN

(without pump and lter) and AC-LNHalso available with ATEX certication.

In order to prevent serious personalinjury and damage to equipment, thehighest possible level of safety must beachieved in such potentially explosivelocations. Numerous requirements interms of laws, regulations, directives andstandards have been issued worldwideto enhance the level of safety.

In the context of globalisation, thesehave been combined, at least in Europe,into harmonised directives for explosionprotection.

In the EU, the so-called ATEX directiveregulates explosion protection (ATEXis the abbreviation of ATmosphaéreExplosible). This directive of theEuropean Parliament and the Council(RL 94/9/EG) which has been in forcesince 1994 regulates “the alignmentof laws of the member states relatingto equipment and protection systemsspecically for use in potentiallyexplosive locations”.

The target group includes amongstothers the manufacturers of equipment.

Following a revision in July 2003,all new equipment must be realisedaccording to this directive. This directiveapplies to areas where potentiallyexplosive gases and dust are presentand also in mining.

Air Cooler Industry / Mobile AC-LN / AC-LNH ATEX Version

Certied to ATEX EU Directives

Product Features

Available for operating in potentially explosive areas are air coolers with AC motor(AC-LN) and air coolers with hydraulic motor (AC-LNH).

The certication applies for a frequency of 50 Hz and 60 Hz versions.

The components are developed especially for use in potentially explosive areas:

1 ATEX certied motor (protected against gas and dust)

2 Stainless steel screws with special washer earthing

3 Antistatic fan with plastic fan blades

4 All components earthed / Cable earthing between motor screw and housing

Corrosion protection CPLThe CPL version (corrosion protectionlevel) is for aggressive ambient condi-tions, such as industrial atmospheres,high humidity or high salt content,which place great demands on thecorrosion resistance and robustness ofthe materials used.

Thermal bypass Hydraulic motor /variable speedThe thermo valve is a pre-controlledpressure valve with temperature-dependent pressure control and ismounted on the hydraulic motor inplace of the existing cover plate.

The pressure setting of the valveautomatically changes dependent onthe temperature and thus controls themotor speed. In addition to the actualtemperature-controlled pressure setting,a mechanical maximum pressure controland a recharging valve are tted asa non-return valve.

The switching temperature valuescan be set from 40 to 70 °C andthe pressure can be controlled upto 100 °C: please contact our salesfor the dimensioning of the thermo-bypass.

All the standard hydraulic motors canbe used with the thermo-bypass.The minimum oil pressure at whichthe thermo control starts to work is 8 bar,

i. e. a maximum residual powerconsumption corresponding to 8 barsis to be foreseen also in by-pass phase.

Mobile CoolersCMS – Cooling Mobile System

General

The Emissions Directive for engines in mobile machinery has been structured toreduce emissions progressively which can lead to a drastic increase in the required

heat dissipation and a corresponding adjustment in cooler size. The limited installationspace available in a mobile machine must therefore be utilised efciently andintelligently.

In mobile machines, multiple cooling circuits can be combined togetherin various ways in a CMS mobile cooler:

l Charge air cooling

l Coolant cooling

l Oil-cooling:gearbox, hydraulics,fan drive, axles

l Fuel cooling

l Condenser

If required, a heat exchanger for the A/C condenser canalso be integrated into the cooling system

Product Features

The cooler comprises a set of cooling elements in different layouts,either side-by-side or front-to-back. With the addition of a fan cover,a protective grille and a fan (also available with motor) this cooler packageis supplied to the customer ready for installation.

KULI simulation software is used to determine the optimal combination andconguration of heat exchangers and fan. In addition, CFD software can be usedto visualise and calculate air ow and heat management in the engine compartment.This helps to reduce development costs.

Special cooling ns ensure suitability for use in dusty environments,for example, in agriculture and forestry or for applications in the mining sector.

Options

Fan controls

The efciency of a cooler also depends largely on the fan control.

For DC and hydraulic motors, various options are used, such as the electronicspeed control ESC, the temperature bypass TB or a proportional valve thatcontinuously adjusts the fan speed according to the uid temperature.

This means that the fan speed can be tailored directly to the required coolingcapacity, i.e. just sufcient power is supplied to the fan as is immediately required.

As an option, these controls can also be supplied with a reversing function

to “purge” the cooler of coarse contamination, such as lint, paper or fragmentsof vegetation.

General

Plate heat exchangers are used wherever thermal energy (heat)has to be transferred from one uid to another.

The advantage is that they can maintain the uid temperature at a verylow and stable level – depending on the temperature of the coolant.

Plate heat exchangers consist of a stack of stamped heat exchange plateswhich are either brazed together or bolted together in a frame with gaskets.

Medium ows in the channels between the plates where hot medium (which will becooled) alternates with cold medium (which will be heated). The design of the platesinduces the turbulent ow required for efcient heat transfer.

Brazed Plate Heat ExchangersHYDAC HEX Sxxx

The design and construction of the brazed plate heat exchangers are particularly

compact and efcient. The heat transfer plates are made in stainless steel and arebrazed with copper as standard. For use with aggressive media, nickel braze can alsobe used.

Copper brazed plate heat exchangers are pressure resistant up to 30 bar,nickel brazed up to 10 bar. Special models are however also suitable for higherpressures.

Gasketed Plate Heat ExchangersHxxx-LIQUID

Gasketed plate heat exchangers are particularly suitable for large ows andhigh cooling capacities. The stack of heat transfer plates and gaskets is clampedtogether with bolts in a frame.

This means that the plate heat exchanger can also be dismantled for cleaning andmaintenance. Furthermore it is possible to add more plates at a later date to achievea higher capacity.

For applications with seawater, the plate heat exchangers can also be suppliedwith titanium heat transfer plates.

Various stamp designs can cater for heavily contaminated or high viscosity uidsto suit particular applications, or even if the temperature difference between the hotand cold medium is only minimal.

Safety heat exchangers with double-walled plates are used in situations wheredifferent media must be strictly isolated.

With brazed plate heat exchangers it is possible to reversethe inlet and outlet connections of a medium without adverselyaffecting the function. However, to guarantee the counterowprinciple, the inlet and outlet of the other medium must alsobe changed. However, changing the cold and hot side is notrecommended. The plate heat exchangers are designed to havehot uid always owing through the outer plate. If cold mediumows through, condensation could form on the outside of theheat exchanger.

With gasketed plate heat exchangers it is not possible tochange the connections because of the more complex platestamp pattern. In this case the connections can be selectedbefore manufacture of the plate heat exchanger.Please consult our technical sales department.

In counterow, the hot medium is cooled more rapidly than in parallel ow because the cold medium ows in the opposite directionto the hot uid.

General

With plate heat exchangers, the heatfrom the uid being cooled is transferredto a cooling uid. The advantage is thatthey can maintain the uid temperatureat a very low and stable level –depending on the temperature of coolant.Brazed heat exchangers thereforeensure efcient heat transfer combinedwith compact dimensions and lowweight.

Product Features

Brazed heat exchangers consist of astack of stamped heat transfer plateswith connections in stainless steel.The plates are vacuum brazed withcopper or nickel.

The plates have smoothed edges andthe end plate is provided with edgeprotection.

The special stamp pattern of theplates induces a turbulent ow whichis necessary for optimum heat transferand which in addition has a self-cleaningeffect because the high level of wallfriction reduces deposits on the surface.

GasketedPlate Heat ExchangersHxxx-LIQUID

General

With plate heat exchangers, the heatfrom the uid being cooled is transferredto a cooling uid. The advantage is thatthey can maintain the uid temperatureat a very low and stable level –depending on the temperature of coolant.

Gasketed plate heat exchangers areparticularly suitable for large ows andhigh cooling capacities and are thereforea useful supplement to the brazed range.

Product Features

Gasketed plate heat exchangers consistof a stack of individually stampedheat transfer plates and gaskets. Theplate stack is clamped using bolts in aframe consisting of a xed cover anda moveable cover. The advantageis that the plate heat exchanger canalso be dismantled for cleaning andmaintenance. Furthermore it is possibleto add more plates at a later date toachieve a higher capacity.

There are several sizes with varyingnumbers of plates and different stampdesigns available to cover the capacity

range. In this way they can cater forheavily contaminated or high viscosityuids, or even if the temperaturedifference between the hot and coldmedium is only minimal.

Note regarding tubingpressure differences (ow loss)

l Simplied for hydraulic oils:

l Inuence of the interior diameter on ow losseswith the following example values:

l = 1 m, Q = 150 l/min, g = 200 mm²/s

l Observations apply only for straight pipes

l Additional threaded joints and pipe bends increase ow loss

Note:

l As few threaded connections as possible

l Few pipe bends – where bends are used, with large bending radius l Difference in height between pump and oil level as small as possible

l Hoses must be suitable for a vacuum of min. 5,000 mmW(e.g. by means of steel wire insert)

l Do not reduce the pipe cross-section determined by the threaded connection

HYDAC COOLING GMBH

Notes

On piping

The pressure differential in a hydraulic line is dependent on:

l Flow rate

l Kinematic viscosity

l Pipe dimensions and can be estimated for hydraulic oils as follows:

Δp[bar] = 5.84 x

l [m]

x Q x v [bar]d4

[mm]

l = Pipe length [m]d = Internal diameter of pipe [mm]Q = Flow rate [l/min]n = Kinematic viscosity [mm²/s]

This applies to straight pipe runs andhydraulic oils, and to laminar ow.

Additional threaded connections and pipe bends increase the pressure differential.

Notice


l Few pipe bends; if unavoidable, use large radius

l Difference in height between pump and oil level as small as possible

l Hoses must be suitable for a vacuum of min. 5,000 mmW

l Do not reduce pipe cross-section predetermined by the unit

Product Features

Continuous cooling and ofine ltrationextend the service life of the oil and ofthe gears. The duplex lter enables thelter to be changed without switchingoff the unit. In addition, there is anintegrated thermal bypass valve whichensures that the system continues to runeven at low temperatures because thecold oil is not fed through the plate heat

exchanger. Once the oil is warm enoughit can ow through the heat exchanger tocool the unit.

To guarantee a constant oil temperaturean optional water ow controller can betted which supplies just enough water tothe plate heat exchanger as is necessaryto achieve the required oil temperature.Pressure, temperature or ow ratesensors can also be added to the controlblock.

l Gear pump

l Filter (duplex lter available as an option)

l Oil-water plate heat exchanger (brazed or gasketed)

Fluid Cooling SystemsFLKS / FWKS / RFCS / HCC

General

The heat arising from internal thermal loss in main spindles, drives,control cabinets, cooling lubricants and hydraulics can be channelled

away very effectively by uid cooling.

Using HYDAC chiller systems with air cooling, water cooling or compressorcooling allows all requirements to be fullled and a constant cooling temperatureto be achieved.

Energy-efcient control systems, such as the speed control used for fan drives,not only reduce noise levels but also provide signicant energy savings.

Performance-controlled compressor cooling units allow operation to be adjustedto suit requirements, saving energy while achieving temperature control accuracyof ±0.2 K. Using the patented mixer-valve system in conjunction with an immersionpump allows this exact set-up to be realized inexpensively and with preciseregulation.

l Can be used as a temperature-controlled intermediate circuit.In this way the contamination and corrosion in the coolant circuits whichcould arise as a result of direct cooling with poor water quality is prevented.

Function

The pump conveys the cooled operating uid from the tank through the component

that is to be cooled. Once there, it absorbs the heat. It then ows back to the plateheat exchanger, where it is returned to a cooler temperature by the cooling water.

Advantages

l Cooling to below ambient temperatures also possible(depending on temperature of the cooling uid)

l Using immersion pumps

l Low release of heat to surroundings and low noise emission

l Thermostatically or electronically controlled proportional valve available asan option: the temperature of the operating uid can thus be maintained ata specic temperature value.

Open-Loop Speed Control

The temperature sensor of the FLKS-2EC5 measures the water-glycol outlettemperature from the cooling system. The 0 – 10 V analog signal of the sensoris assigned a temperature range of +25 up to +45 °C. The signal is forwarded tothe EC fan according to the measured uid outlet temperature to control the speed.The fan switches on at 1.5 V (= +28 °C) and reaches its maximum speed at 10 V(= +45 °C).

Even at low ambient temperatures, the uid temperature cannot drop below+28 °C given constant power input. This prevents condensation on electricalcomponents.

Application:

Specially suited for low air temperatures, e.g., outdoors

Closed-Loop Speed Control

The FLKS-2EC3 also comes with a PID controller. The temperature sensor measures the uid outlet temperature (variable).This temperature is continuously compared to the reference value (ambient temperature + set differential ΔT).The PID controller continuously adjusts the speed to keep the uid temperature near the ambient temperature.

The outlet temperature remains at a set differential above the ambient temperature regardlessof the input temperature of the uid (power of the machine).

Application:Primarily precision cooling (e.g., in machine tools)

Lower fan speed

= lower noise level= lower energy consumption= lower contamination level

General

The FLKS-4EC is a compact uid/air cooling system with a plastic tankhousing, integrated air duct, pump andvariable-speed fan. This lightweightand robust design makes it suitable fordiverse applications.

Function

The pump conveys the operating uidfrom the tank through the part beingcooled to the heat exchanger. The axialfan provides the necessary air ow

through the heat exchanger to cool theoperating uid. The speed can varydepending on the application.

The temperature sensor of the FLKS-4EC5 measures the water-glycol outlettemperature from the cooling system. The 0 – 10 V analog signal of the sensoris assigned a temperature range of +25 up to +45 °C. The signal is forwardedto the EC fan according to the measured uid outlet temperature to control the speed.The fan switches on at 1.5 V (= +28 °C) and reaches its maximum speedat 10 V (= +45 °C).

Even at low ambient temperatures, the uid temperature cannot drop below +28 °Cgiven constant power input. This prevents condensation on electrical components.

Application:



The FLKS-4EC3 also comes with a PID controller. The temperature sensor measures the uid outlet temperature(variable). This temperature is continuously compared to the reference value (ambient temperature + set differential ΔT).The PID controller continuously adjusts the speed to keep the uid temperature near the ambient temperature.

FLKS – Systematic Control

Noise reduction and energy savings – these are two of the biggest issuesof the future in mechanical engineering.

FLKS – Fluid-air cooling systems – cooling, as the name indicates, with air. A fan ensures that the necessary air ow is present to cool down the warm uidin the cooling element. In a conventional fan with a xed speed, the fan beginsto run as soon as the cooling system starts up, irrespective of the ambienttemperature and the power input from the actuator. This fan constantly uses energyand creates permanent noise.

Systems with open-loop and closed-loop speed control can change this:at low ambient temperatures the fan still runs but at a low speed; if the inlettemperature to the cooler is only just over the needed outlet temperature(e.g. if the machine is at a standstill due to a tool change and thereforeonly a little heat is fed into the medium), the speed is also reduced.

Lower speed

= lower noise level

= lower energy consumption

= lower contamination level

= no condensation in electricalcomponents at low ambienttemperatures

The FLKS-EC HYDAC Cooling seriesoffers various possibilities for open-loopand closed-loop control. This meansthe right solution can be found for everyapplication.

It is available in sizes FLKS-2EC,FLKS-3EC, FLKS-4EC, FLKS-5EC andFLKS-6EC.

FLKS with Open-loop Speed Control (FLKS-xEC5)

The FLKS with an EC fan drive is also equipped with a temperature sensor. The analog signal 0 – 10 V of the sensor is assigneda temperature range of +25 up to +45 °C. An analog signal is forwarded to the EC fan for open-loop control according to the uidoutlet temperature measured. The fan switches on at 1.5 V (= +28 °C) and reaches its maximum speed at 10 V (= +45 °C).

This FLKS is particularly suited to outdoor installation (e.g. for inverter cooling in cogeneration plants).

FLKS with Closed-loop Speed Control (FLKS-xEC3)

Closed-loop control is when measurements are continually taken to determine to what extent the control variable correspondswith the reference variable and – in contrast to open-loop control – a deviation automatically leads to adjustment of the controlvariable.

A temperature sensor measures the outlet temperature (control variable). This is continuously compared with the referencevariable (ambient temperature + ΔT). The PID controller continually adjusts the speed of the fan, in order to align the outlettemperature with the ambient temperature.

The FLKS with closed-loop speed control is mainly used in machine tools where high uid temperature accuracy is required.

FLKS with closed-loopspeed control:

Temperature trendwith uctuating power input.

The outlet temperature remainsa xed difference (∆T) above theambient temperature irrespectiveof the input temperature of the uid(power of the machine).

FLKS without speed control:

Temperature trendwith uctuating power input.

The outlet temperature of the uiductuates according to the power input.During machine downtimes it almostreduces to ambient temperature.

Fluid-WaterCooling SystemsFWKS

General

The FWKS is a compact uid/watercooling system with a tank, circulatingpump, plate heat exchanger and optionaltemperature control.

The FWKS is primarily used as anintermediate circuit. The advantageof an intermediate circuit is that thesystem or the parts being cooled onlycome into contact with the operatinguid and not the coolant water itself,which helps prevent the system frombecoming contaminated or corroded.

Function

The pump conveys the operating uidfrom the tank through the part of theconsumer being cooled.

The operating uid absorbs the heat andows through the plate heat exchanger,where it is cooled by the coolant owingin the opposite direction.

The operating uid is then fed backto the tank.

Inletoperating uid

Outletoperating uid

Outletcoolant

Inletcoolant

Control OptionsIn unregulated systems, the maximum quantity of coolant is always pumped through the plate heat exchanger regardlessof the power input of the consumer. The FWKS with temperature control can change that by adding a valve that adjuststhe amount of coolant to the requirements of the consumer. This means only the coolant that is needed to maintainthe specied ow temperature is used. This is why regulated systems are particularly energy-efcient and conservative.

The FWKS series offers a number of control and regulating options.This means the right solution can be found for any application.

Mechanical temperature control version

This version uses xed value regulation.The desired ow temperature is set manually. A temperature sensorin the tank measures the temperature of the operating uid. The integrated

proportional valve adjusts the amount of coolant to the power requirementsof the consumer.

Application:

l Fixed value control to ±3 °C

l Power cooling

l Protection against condensation

l No electricity required for controller

Electronic temperature control version

Sensors measure the uid and air temperature, which is analyzedby the temperature controller. An integrated proportional valve adjuststhe amount of coolant to the needs of the consumer.

This makes it possible to keep the uid temperature the same as the ambienttemperature (air or machine base temperature).

Application:

l Precision cooling to ±0.5 °C

l Protection against condensation

l Fixed value setting or differential temperature regulation

Centralized Cooling Systems

RFCS water-chillerwith heat exchanger and HY-ECOBOX

RFCS water chiller: The RFCS is used to prepare cold water.Regardless of the particular ambienttemperature, cold water can be providedin a wide range of capacity classes andfed to the customer application.

The unit is a water-cooled water chiller.The plate heat exchanger condensertransfers its process heat to a separatecooling-water circuit.

Heat exchanger: RFCS cooling units with water-cooledcondenser require a cooled water supplyfor heat removal. A heat exchanger isused when it is either not practical or notdesirable to utilize mains water.

HY-ECOBOX: The HY-ECOBOX is an optional modulewhich contributes to improved energysaving: when the ambient temperaturedrops below a certain level, the coolingmachine's active cooling is switched off.The system then operates in passivecooling mode, using the heat exchanger.This energy manager can thereforeonly be used in combination with a heatexchanger.

Advantages:

l Saves resources,as no water is used

l High energy-saving potential

thanks to the HY-ECOBOX* l The RFCS transfers no heatinto the building

* ECOBOX: optional accessory forpassive free cooling operation
